์์ฉ ๊ธฐ์ : Hyaluronate sodium provides both mechanical and pharmacological benefits to the diseased joint: * **Mechanical Support:** Restores the viscoelastic properties of synovial fluid, providing a cushioning effect and boundary lubrication for articular cartilage. * **Anti-inflammatory Pathway:** * **Free Radicals** โ Scavenged directly by HA molecules, reducing oxidative damage within the joint capsule. * **Prostaglandins** โ Synthesis and release are suppressed, mitigating local inflammation and pain. * **Cellular Modulation:** Reduces the influx of inflammatory proteins and leukocytes into the joint space. Interacts with **CD44 receptors** on synoviocytes and macrophages to downregulate pro-inflammatory cytokines.

- Injection through skin that has been recently fired or blistered
- Injection through skin with excessive scurf or counterirritants
- Use as a substitute for adequate diagnosis (e.g., failing to rule out fractures via radiography)
- Hypersensitivity to hyaluronate or any component of the formulation
์ด์๋ฐ์
- Local joint flare (heat, swelling, and/or effusion) post-injection
- Increased incidence of flares when combined with other intra-articular drugs
